This paper presents backscatter analysis of L-band land clutter data, measured from an airborne platform, over various terrain types encountered in the Western Cape region of South Africa. The data processing steps are ...

Although the quadrature mixing radio front-end offers an attractive way to perform frequency translation, its image-rejection capability is severely affected by the gain and phase imbalances (I/Q imbalances) between its ...

High range resolution (HRR) radar measurements can provide important feature information when performing non-cooperative target recognition. This paper presents a joint development of a mobile, X-band, HRR research radar ...

This paper describes a simple process for the generation of arbitrary probability distributions of complex data with correlation from sample to sample, optimized for hardware in the loop radar environment simulation. ...

Despite the advantages that quadrature mixing offers to radio front-ends, its practical use has been limited due to its sensitivity towards gain and phase mismatches between its in-phase and quadrature channels. DC offsets ...

A dechirp on receive (DoR) concept demonstrator was recently implemented on the Fynmeet radar system of the CSIR, in an attempt to extend its high range resolution (HRR) measurement capabilities. Based on the low dynamic ...

A quadrature mixing front-end is well-suited toward software define radio (SDR) applications, due to its low complexity and the inherent flexibility that it affords the radio front-end. Its performance is, however, severely ...
